Various embodiments can advantageously allow for application of one ormore types of therapy (e.g., phototherapy, heat therapy, cold therapy,massage therapy, combinations thereof, etc.) to a user's body. Variousembodiments can enable two or more different types of therapy to beapplied to a user's body generally simultaneously. Yet other embodimentscan enable different types of therapy to be applied at different times,for example, in a predetermined sequence, alternating pattern, etc. Anyof the various aspects of the present invention disclosed herein can beused individually or in combination with any one or more of the otheraspects.

FIG. 1 illustrates an exemplary therapeutic device 100 embodying one ormore aspects of the present disclosure. As shown in FIG. 1, thetherapeutic device 100 includes a container 104. The device 100 alsoincludes one or more light sources 108 for emitting therapeutic light112 and means, within the container 104, for applying heat therapyand/or cold therapy to a user's body.

The container 104 can be formed from a wide range of materials.Exemplary materials include polymers, plastics, flexible materials,rigid materials, materials capable of being mass produced withrelatively low manufacturing costs, among others.

In the exemplary embodiment shown in FIG. 1, the light sources 108 areshown within the container 104 directing therapeutic light 112 throughthe container surface 116. The container surface 116 is formed of alight-transmissive material that allows the light 112 to passtherethrough. Alternatively, the container surface 116 may be opaque andprovided with openings or holes to allow the light 112 to escape or passthrough the holes for application to a user's body.

In addition, exemplary embodiments can include a container 104, or atleast portions thereof, which are sufficiently flexible or bendable toallow the device 100 to be conformed or contoured to a portion of auser's body. By way of example, the container 104 can be formed from amaterial having sufficient elasticity or flexibility to be wrapped atleast partially around a particular portion of a user's body (e.g., arm(FIG. 10), leg, finger, etc.). Alternatively, the container, or at leasta portion thereof, can be formed from a relatively rigid material.

The container 104 can be provided in a wide range of shapes and colors.In the illustrated embodiment, the container 104 is generallyrectangular. Alternatively, other embodiments include containers invarious other geometric shapes, fanciful shapes, recognizable andwell-known shapes. Exemplary container shapes include spherical,circular, semicircular, triangular, diamond shaped, discs, cubes,prisms, mouse head, star, fish, dinosaur, food item, hearts, football,among others. The particular shape of a container can be determined atleast in part by user preference, which, in turn, can be based on anynumber of factors including the user's interests and age.

Further, the container 104, and also the device 100, can be provided invarious sizes. In a preferred embodiment, the container 104 isrelatively compact so that the device 100 is readily portable. The sizeof the therapeutic device 100 and its container 104 can depend, at leastin part, on the particular size of the ailment or body portion to whichthe therapeutic device 100 is to be applied.

In various embodiments, the container 104 can be at least partiallyhollow and define an internal cavity. The cavity of the container 104can be filled (or at least partially filled) with any of a wide range ofagents or substances bearing cold-retaining and/or heat-retainingproperties such as materials generally used in hot/cold gels, reusableice-packs, reusable heating pads, single use hand warmers, refreezableliquids or semi-liquids, reheatable liquids or semi-liquids, Insul-Icereusable ice available from PCM Thermal Solutions, Inc. of Naperville,Ill., among other suitable materials.

By way of example, the container 104 can include a filler adapted toretain heat for an extended or prolonged period of time (e.g., 20minutes, 30 minutes, etc.) after the filler has been heated, forexample, by heating the container 104 in a conventional oven, microwave,hot water, etc. The filler can also, or alternatively, be adapted toretain cold for an extended or prolonged period of time (e.g., 20minutes, 30 minutes, etc.) after the filler has been cooled, forexample, by placing the container within a freezer, etc. By way ofexample only, the filler may comprise a refreezable, reusable, non-toxicliquid gel coolant, which is hermetically sealed in the container 104.

In other embodiments, the container 104 itself can be formed ormanufactured from a material capable of maintaining cold or heat. In yetother embodiments, the therapeutic device 100 can include means forself-generating heat and/or cold. For example, the device 100 caninclude any of a wide range of substances that begin to activate andgenerate their own heat or cold when exposed to air, such as materialsgenerally used in commercially available hand and toe warmers. In suchembodiments, the device 100 can be vacuum sealed within a suitablepackage, and can begin generating heat or cold (as the case may be) whenthe package is opened thereby exposing the device to air.

In further embodiments, the therapeutic device 100 can include amaterial generally used in instant single-use cold compresses (e.g.,ammonium nitrate and water, etc.) and/or instant single-use hotcompresses (e.g., calcium chloride and water, etc.). In suchembodiments, the container 104 can be activated to generate heat or coldby shaking the contents of the container 104 and/or squeezing thecontainer 104 to cause a chemical reaction or phase change of thematerial(s) within the container 104.

The light sources 108 will now be described in more detail. The lightsources 108 can include a plurality of LEDs capable of emittingtherapeutic light. In some implementations, the therapeutic light canprovide energy stimulation to human tissue to increase cellular activityduring the healing process.

The LEDs 108 can be capable of emitting infrared light, near infraredlight, and/or light having a wavelength within a range of about 680nanometers and about 880 nanometers. Alternatively, other suitable lightsources capable of emitting therapeutic light may be employed. Exemplarylight sources include other LEDs, laser, chemiluminescent light sources(e.g., glow sticks, etc.), electroluminescent light sources,bioluminescent light sources, and the like.

The particular type of light source(s) can depend, at least in part, onthe particularities of the ailment for which the therapeutic device isto be used. The selection of light source can also depend, at least inpart, on size and weight restrictions (if any), in which case LEDs maybe selected because LEDs are typically compact, lightweight, and do notgenerate excessive amounts of heat during operation.

Optionally, one or more of the LEDs 108 may produce other forms of lightbesides infrared or near infrared therapeutic light. By way of exampleonly, one or more LEDs 108 may produce colored light, which may alsohave a therapeutic soothing or relaxing effect.

As shown in FIG. 1, each LED 108 is positioned within the container 104.The LEDs 108 are oriented to direct light 112 through the containersurface 116. Alternatively, each LED 108 need not be positioned entirelywithin the container 104. Instead, one or more of the LEDs 108 may bepartially or entirely positioned external to the container 104, forexample, on the container surface 116. Further, each LED 108 need not bepositioned to direct light through the container surface 116. Instead,one or more of the LEDs 108 can be oriented to direct light through thecontainer's sidewalls 120 and/or bottom surface.

In the exemplary embodiment of FIG. 1, the LEDs 108 are arranged in twogenerally parallel rows of five LEDs 108. Alternatively, otherembodiments can include any suitable number of (i.e., one or more) LEDsin various other arrangements and arrays (e.g., large flat arrays, smallarrays, circular arrays (FIG. 5), semicircular arrays, triangulararrays, zigzagging arrays, etc.). The number and arrangement of LEDs candepend, at least in part, on the type and size of ailment for which thetherapeutic device is to be used. The number and arrangement of LEDs canalso depend, at least in part, on size and weight restrictions (if any)placed on the therapeutic device. For example, various embodiments caninclude therapeutic devices that are relatively small, lightweight, andthus suitable for use by lightly equipped, highly mobile specialoperations troops. Because wounds can pose serious physical risk duringcombat operations, lightweight therapeutic devices that promote woundhealing and musculoskeletal rehabilitation and conditioning can beadvantageous.

As shown in FIG. 1, the LEDs 108 are interconnected to a power source124 by conductive leads or paths 128. In the illustrated embodiment, thelight sources 108 and portions of the conductive leads 128 are surfacemounted on (e.g., electronically welded onto, etc.) a flexiblelightweight ribbon cable 132, although other conductive leads andmounting methods are also possible.

The operation of the light sources 108 may be controlled by at least oneswitch 136. The switch 136 may, for example, allow the user to selectfrom among various display modes for the light sources 108, such as anoff-light mode, an on-light mode, a mode in which the light sources 108emit steady or non-flashing light, a mode in which the light sources 108emit light intermittently, a mode in which the light sources 108 blinkat different times in accordance with a predetermined sequence or order,a mode in which the light sources 108 emit light that phases between orblends colors, a mode in which the light sources 108 emit lightrandomly, and/or a mode in which the light sources 108 pulsate tosounds.

In the illustrated embodiment, the switching device 136 is a push buttonswitch for switchably connecting the light sources 108 to the powersource 124. As shown, the switch 136 is positioned within the container104. The switch 136 can be coupled to an externally flexible surfaceportion 116 of the container 104 such that application of externalpressure upon the externally flexible surface portion 116 activates theswitch 136 thereby causing operation of the light sources 108. Theexternal pressure may, for example, be applied by the user squeezing thecontainer 104 at the externally flexible surface portion 116. The switch136 may also allow the user to cycle through the various display modesor select a particular type of light (e.g., therapeutic light, coloredlight, etc.) to be emitted by the light sources 108 by successivelysqueezing the container 104 at about the externally flexible surfaceportion 116. Additionally, the switch 136 may also allow the user to dimor brighten the intensity of the light, for example, by holding down theswitch 136 with continuously applied pressure to the container 104 atabout the externally flexible surface portion 116.

Alternatively, the switch 136 may include one or more other suitableswitching devices or means including electrical terminals for switchablyconnecting the light sources to the power source when the electricalterminals are placed in contact with the user's body, motion-responsiveswitches, light-sensitive switches, temperature-sensitive switches,compression switches, voice activated switches, etc. For example, theswitch may be a light-sensitive switch such that the light sources areactivated when the ambient light level falls below a predeterminedthreshold.

In the illustrated embodiment of FIG. 1, the power source 124 comprisesthree watch batteries 140, 144, and 148 electrically connected inseries. Alternatively, the power source 124 may be any suitable means ofproviding energy to the light sources 108 including renewable batteries,rechargeable batteries, disposable batteries, solar cells, and othersuitable power sources, including kinetic power sources.

A therapeutic device can, but need not necessarily, include anattachment device for attaching the therapeutic device to a user. By wayof example only, FIG. 3 illustrates a therapeutic device 300 thatincludes an adhesive patch 352, and FIG. 4 illustrates a therapeuticdevice 400 that includes an adhesive bandage strip 452, as described inmore detail below.

An attachment device of the therapeutic device 800 in FIG. 8 includes anelastic band 852 attached to opposed ends 856 and 860 of the container804. The elastic band 852 can have a sufficient length and/or elasticityto allow the elastic band 852 and container or eye mask 804 to bedisposed around the user's head, thereby attaching the therapeuticdevice 800 to the user's head.

Or for example, a therapeutic device can be adapted to enable the deviceto be disposed generally around a portion of the user's body (shoulder,knee, back, arm, etc.), with the ends being secured to one another via asuitable attachment mechanism, such as hook and loop closures,adhesives, neoprene material connecting the two opposed ends, etc.

In yet other embodiments, however, the therapeutic device need notinclude a separate attachment device. For example, FIG. 10 illustrates atherapeutic device 1000 including a container 1004 having a sufficientsize and/or elasticity to be disposed and/or stretched around a user'sarm 1064 preferably in a manner that resists unintentional loosening ordetachment of the therapeutic device 1000 from the user but that alsopermits easy removal of the device 1000 from the user. The therapeuticdevice 1000 also includes one or more light sources 1008 for emittingtherapeutic light, and means within the container 1004 for applying heatand/or cold therapy. Alternatively, the therapeutic device 1000 can beadapted to be disposed around other portions of the user's body, such asan ankle, shoulder, leg, back, etc. Again, however, other attachmentdevices may be employed in various embodiments of the invention.

FIG. 2 illustrates another embodiment of a therapeutic device 200including light sources 208 that are removably coupled to a container204. The light sources 208 are capable of emitting therapeutic light212. The container 204 can further include means for applying hot/coldtherapy, such as a hot/cold gel pack.

As shown in FIG. 2, the container 204 defines a sleeve or pocket 268sized to receive the apparatus or packet 272 that includes the lightsources 208, one or more power sources 224, conductive leads 228, and aswitching device 236 for switchably connecting the light sources 208 tothe power sources 224 via the conductive leads 228. Alternatively, othersuitable methods for removably coupling the light sources 208 to thecontainer 204 can be employed.

By removing the light sources 208 from the container 204, the container204 can then be stored (e.g., in a freezer, etc.), heated (e.g., heatedin a conventional oven, microwave, hot water, etc.), and/or cooled(e.g., refrigerated, etc.) separately from the light sources 208.

FIGS. 9A through 9B illustrate a therapeutic device 900 that employschemiluminescence to apply therapeutic light 912 to a user's body. Thetherapeutic device 900 includes two or more agents or chemical solutionsthat emit therapeutic light 912 when combined. The solutions can bemaintained in separate chambers within the container 904, that is, atleast until the therapeutic light 912 is to be applied to the user'sbody.

A first chemical solution or activator can be contained within a readilybreakable container 992 (e.g., a glass vial, etc.) which, in turn, isinside an outer container 904. The outer container 904 includes anotherchemical solution. Sufficiently bending the container 904 (FIG. 9B)breaks the breakable container 992, thereby allowing the two solutionsto flow together resulting in a chemical reaction that producestherapeutic light 912 (FIG. 9C).

Exemplary chemical agents that can be used with the therapeutic device900 include an oxalic-type ester in one of the containers 904 and 992,and a hydroperoxide with a solvent and flourescent compound in the othercontainer 904 or 992. The therapeutic device 900 can include a widerange of two part combinations of flourescing agents, which preferablyare relatively efficient at producing light over an extended period oftime, biodegradable, and/or safe for the environment.

The device 900 can also include means for applying hot/cold therapy. Forexample, the device 900 can include any of a wide range of agents orsubstances that begin to activate and self-generate heat or cold whenexposed to air. Exemplary materials include those ingredients generallyused in hand and toe warmers. For example, the device 900 can include amixture of various ingredients including iron, charcoal, water, salt,wood fiber, and vermiculite, among other suitable combinations. Whenexposed to the air, these ingredients can combine and react such that anoxidation process takes place producing heat. In such embodiments, thedevice 900 can be vacuum sealed within a suitable package that must beopened to expose the device 900 to air. Accordingly, the device 900 canthus be made to apply both therapeutic light and hot/cold therapy (asthe case may be) to the user's body by bending the container 904 tocrack open the internal breakable container 992, and by opening thepackage to expose the device 900 to air.

In another embodiment, the device 900 can include a hot/cold gel withinthe container 904. In which case, the device 900 can apply boththerapeutic light and hot/cold therapy to the user's body by heating orcooling the device 900 to a non-ambient temperature (i.e., a temperaturemore or less than ambient temperature), and bending the container 904 tocrack or break open the internal container 992.

In various embodiments, a therapeutic device can include an outercontainer in which is positioned a filler material (e.g., a hot/cold gelor agent, etc.) and a substantially fluid-tight inner container withinthe outer container. At least one light source for emitting therapeuticlight, at least one power source for powering the light source, and aswitching device (e.g., push button switch, a dome push switch, amembrane switch, etc.) can be encapsulated or housed within the innercontainer, preferably in a fluid-tight fashion. The inner container canbe suspended within the filler material and/or coupled (e.g., adhered,affixed, mounted, etc.) to an inner surface of the outer container. Theouter container can include at least one externally flexible portioncoupled to the switching device within the inner container such thatmovement of the flexible portion activates the switching device toconnect the light source(s) to the power source(s). In variousembodiments, the entirety of the outer container can be sufficientlyflexible such that applying pressure (e.g., squeezing, compressing,etc.) to the outer container compresses the filler material (e.g.,hot/cold gel, among other substances, etc.) within the outer container.In response to the compression, the filler material, in turn, cantransmit a compression force to the inner container causing the switchto activate to connect the light source(s) to the power source(s). Inembodiments in which the filler material is freezable, the innercontainer may include an internal cavity or gap for enabling the fillermaterial, even when frozen, to transmit a compression force initiallyapplied to the outer container to the inner container for activating theswitching device therein.

Various therapeutic devices (e.g., 100, 200, 300, 400, 500, 600, 700,800, 900, 1000, etc.) can be provided in a wide range of shapes andsizes, which can depend, at least in part, on the particular ailment orbody portion to which the therapeutic device is to be applied.

Various embodiments can also include therapeutic devices defining one ormore external and/or internal indicia. The indicia can include a widerange of graphic images, graphic elements, designs, artwork, distinctivemarks, identifying symbols, company logos, alphanumeric characters,advertisements, trademarks, sports team insignias, names, monograms,among others. The indicia can be positioned relative to the lightsources such that the light sources direct light at the indicia tohighlight (e.g., illuminate, backlight, etc.) the indicia. Such indiciacan impart holiday themes, professional themes, promotional themes,sports related themes, and the like. Indeed, any suitable theme may beemployed and are not limited to these types of themes described above.

Optionally, various embodiments can include a plurality oflight-altering particles (e.g., glitter, reflective particles,refractive particles, translucent particles, glass-like prisms, coloredparticles, clear particles, etc.) within the container (e.g., suspendedwithin the hot/cold gel or other suitable substance within thecontainer). These particles can receive and alter the light from atleast one of the light sources to create yet an additional feature. Forexample, the altered light can produce a visibly pleasing or sparklinglight effect. Indeed, various embodiments can produce such visiblypleasing light effects that a user may simply choose to use the devicefor novelty or display purposes rather than for therapeutic purposes.

Another aspect of the invention provides a method of applying therapywith a therapeutic device. The therapeutic device includes one or morelight sources capable of emitting therapeutic light and also includes atleast a non-ambient portion having a temperature greater or less thanambient temperature. In an exemplary implementation, the methodgenerally includes applying the non-ambient portion to a user's bodywith the light source directed to emit therapeutic light toward theuser's body. The therapeutic device can then be used to apply heat orcold therapy and/or therapeutic light to the user's body.

The method can also include heating or cooling the therapeutic deviceprior to applying the non-ambient portion to the user's body. Thetherapeutic device can also include an attachment device which is usedto attach the therapeutic device to the user's body.

The therapeutic device can also include a massager. In which case, themethod can further include using the therapeutic device to, generallysimultaneously or at different times, apply heat/cold therapy, massagetherapy, and/or therapeutic light to the user's body.

Accordingly, various implementations advantageously allow for readyapplication of one or more types of therapy (e.g., light, heat, cold,massage, a combination thereof, etc.) to a user's body. Variousimplementations enable two or more types of therapy to be applied to auser's body generally simultaneously. Yet other implementations enabledifferent types of therapy to be applied at different times, forexample, in a predetermined sequence, alternating pattern, etc.

Various embodiments can include therapeutic devices capable of beingused repeatedly for applying hot therapy, cold thereapy, therapeuticlight, massage therapy, and/or combinations thereof. Yet otherembodiments can include single-use, disposable therapeutic devices.Various embodiments of a therapeutic device can also be configured to beneutrally buoyant, positively buoyant, or negatively buoyant when placedin a liquid.

Various embodiments can also include at least one power source spacedapart or remote from a therapeutic device. In such embodiments, at leastone remote power source (e.g., rechargeable battery pack, wall outlet,etc.) can provide the electrical power for operation of the therapeuticlight source(s). The light source(s), in turn, may be electricallyconnected to the at least one remote power source by electrical wiringor cords (e.g., an insulated flexible electric wire fitted with a plug,etc.). This can also allow for heating and/or cooling of the therapeuticdevice without also having to heat or cool the power source(s).
